Trapezoidal fill sheet for low silhouette cooling tower

Abstract

The vertical height requirement of a cooling tower is reduced by utilizing trapezoidal shaped fill sheets which are suspended generally in line with the entering air stream so as to form a wedge shaped plenum space beneath the lower sloped edges of the fill sheets.

What is claimed is: 
     
       1. An improved substantially flat fill sheet for a cooling tower, said fill sheet comprising: a trapezoidal face portion extending between two nonparallel edges and unequal opposite sides connected between said edges; said face portion terminating at said edges and said sides, said face portion having a surface with contours defining pathways for a fluid and said face portion including spacer projections on its said surface.   
     
     
       2. A pair of fill sheets according to claim 1, each of said fill sheets having two nonparallel edges of unequal length and two unequal opposite sides extending substantially perpendicular to the shorter of said nonparallel edges, said face portions of said pair of sheets being substantially congruent along the longer of said two nonparallel edges and which form a common line of severance substantially angularly bisecting a rectangular sheet originally comprising said pair.
